NHER 33258 (Monument record) - Ringland Hills

Pit, conical, about 3m deep, 6m across. Very steep sided, set in foot of slope.
Apparently full of flint nodules though base covered in dead leaves. Hidden by vegetation before 1997; a few meters south of unofficial path following edge of public access land.
Bearing in mind the flint mine/pit at NHER 7798 (context 1), and the scatter of flint-mine type finds at NHER 20014 adjacent, this seems a good contender for a flint pit.

Matters have worsened, the assault course has been made more permanent with earth banks, wooden ramps etc. and the pit partly infilled as a kind of wall-of-death.

The area around the grid reference recorded in 1997 (TG 1378 1259) was examined in detail and no pit matching the description above was located. The feature described was discovered further to the east at TG 13835 12568.
The banks and ramps recorded in 2004 were not seen, although mountain bike tracks and a mound of soil in the base of the pit were evident. The area around the pit had recently been bulldozed (see S1).
The pit could be a prehistoric flint mine. However, it could equally be a more recent quarry pit or a bomb crater. A low irregular bank up to 0.5m high surrounds the outer edge of the pit (possibly upcast from quarrying or material displaced by an explosion).

The location and description of this pit is consistent with it being one of the shell craters associated with a World War Two tank training area (NHER 53659) located on Ringland Hills. A pit, almost certainly a shell crater, is visible on aerial photographs at this point (S2-S4).
